customerActivate INTERNAL_SERVER_ERROR

Please help,

This mutation has been working for a while, but for some reason we are now getting errors

Here is the mutation.. (I tried removing the @inContext without much luck)

mutation customerActivate($country: CountryCode, $id: ID!, $input: CustomerActivateInput!)
  @inContext(country: $country) {
    customerActivate(id: $id, input: $input) {
      errors: customerUserErrors {
        ...CustomerUserError
      }
      accessToken: customerAccessToken {
        ...AccessToken
      }
      customer {
        ...CustomerSummary
      }
    }
  }
  
  fragment CustomerSummary on Customer {
    acceptsMarketing
    createdAt
    defaultAddress {
      ...AddressFull
    }
    displayName
    email
    firstName
    id
    lastIncompleteCheckout {
      id
      webUrl
      updatedAt
    }
    lastName
    phone
    tags
    updatedAt
  }
  
  fragment AddressFull on MailingAddress {
    address1
    address2
    city
    company
    country
    countryCode: countryCodeV2
    firstName
    formattedArea
    id
    lastName
    latitude
    longitude
    name
    phone
    province
    provinceCode
    zip
  }

  
  fragment CustomerUserError on CustomerUserError {
    code
    field
    message
  }

  
  fragment AccessToken on CustomerAccessToken {
    token: accessToken
    expires: expiresAt
  }

  
  fragment AddressFull on MailingAddress {
    address1
    address2
    city
    company
    country
    countryCode: countryCodeV2
    firstName
    formattedArea
    id
    lastName
    latitude
    longitude
    name
    phone
    province
    provinceCode
    zip
  }

 {
  id: 'Z2lkOi8vc2hvcGlmeS9DdXN0b21lci81ODAxMjY1MjM0MTA0',
  country: 'US',
  input: {
    activationToken: 'd1c22e8b894954e01ae85e77e8e95b39-1645151885',
    password: '54321'
  }
}

and there is the response

      "message": "Internal error. Looks like something went wrong on our end.\nRequest ID: 311386cd-b4ea-4d48-992e-a63c6464fa3f (include this in support requests).",

      }
    }
  ]
}
